Unit 4 Going green Lesson 1 The earth is heating up.（课件+素材）- 2026-2027学年冀教版（三起）英语六年级上册

为什么会有全球变暖呀呀北极熊冰冰住在北极的冰山上，可最近他总觉得脚下的冰块在慢慢变小，连平时厚厚的积雪都少了好多，这到底是怎么回事？难道太阳公公变得更热了吗？冰冰最喜欢在冰面上滑来滑去，和小伙伴们玩抓小鱼的游戏。以前北极的冬天总是冷冷的，冰山像巨大的水晶城堡能一直待到春天，可这几年春天来得越来越早，冰山融化的也越来越快，有时候冰冰还没玩够，脚下的冰块就咔嚓一声裂开了小缝。妈妈，为什么冰块越来越少了呀？冰冰趴在妈妈背上，看着渐渐融化的冰水问。熊妈妈叹了口气，指着远方说，你看，人类开着会冒烟的汽车工厂里也会排出好多热气，这些热气像一层厚厚的玻璃罩，把地球妈妈盖得严严实实的。太阳的热量跑不出去，地球就变得越来越暖和，这就是全球变暖哦。这时冰面上跳出来一个带着雪花围巾的气候小精灵，手里捧着一块正在慢慢融化的冰块。冰冰，你知道吗？地球妈妈本来有一件保温衣，是由二氧化碳这些气体组成的，能让地球保持暖暖的，不被冻成大冰球。可现在人类用了太多煤、石油，开太多汽车，保温衣变得越来越厚，就像给地球妈妈裹了太多棉被，热的喘不过气了。小精灵指着远处的冰川说，北极和南极的冰块最怕热了，温度一高就会融化，海平面就会慢慢上升，好多小动物的家都会被淹掉，而且天气变热了，有的地方会很久不下雨，小草会枯死，有的地方又会下好大的雨，把房子都淹了呢。冰冰着急的问，那我们能做些什么呢？妈妈笑着说，别担心，人类已经在努力了。他们开始少开汽车，多走路或骑自行车。还种了好多好多树，树能吃掉那些让保温衣变厚的气体。工厂也在想办法少排热气，让地球妈妈慢慢凉快下来。小精灵点点头。我们也可以帮忙呀。比如节约用电，少用一次性的东西，这些都会让保温衣慢慢变薄哦。从那以后，冰冰每天都会观察冰山的变化，他听说远方的小朋友们正在种树，节约用电，心里就暖暖的，他相信只要大家一起努力，地球妈妈一定会慢慢凉快下来，北极的冰山也会变回原来的样子宝贝，你感觉到天气的变化了吗？其实保护地球妈妈，让她不那么热，我们每个人都能出份力哦。快和大家说说你平时会怎么做呢？是帮爸爸妈妈关灯省电，还是会和小伙伴一起去种树呀？ Less than one, the earth is heading up.
